While other solar forecasting systems take more narrow location and timeframe views, whats different about the IBM approach is that we incorporate a great number of weather and solar energy prediction models. We then blend those using historical data as a function of weather situation, forecast horizon and location to create what we call a supermodel.
Were extremely close to reaching the point at which renewable electricity costs as little to generate as electricity from fossil fuels, so its imperative that we dont take a backward step.
